Final answer:
To save and transfer a custom set of color swatches to another computer, use the 'Swatches' panel to save them as a swatch library file (.aco for Photoshop, .ase for Illustrator) and transfer this file to the other computer.
Step-by-step explanation:
To save a custom set of color swatches and transfer them to another computer using a graphics or design program, you'll typically want to use the 'Swatches' panel. The process generally involves opening the Swatches panel, selecting your custom color swatches, and then saving them as a swatch library file. This file can then be transferred to another computer and loaded into the software on that system.
For example, in Adobe Photoshop, you can go to the Swatches panel, click on the small menu icon in the top right corner, and select 'Save Swatches for Exchange'. This will create an aco file that can be imported into Photoshop on another computer. Similarly, Adobe Illustrator uses a .ase file format for exchangeable swatch libraries.
Remember to store the file in a location that you can easily access for the transfer, such as on a USB drive or a cloud storage service. Once you are on the other computer, you can typically load the swatches back into the program via the Swatches panel by choosing the option to 'Load Swatches' or 'Import Swatches'. The exact wording may vary depending on the software being used.
